We subscribe to Contact Monkey to track e mail open rates. They recently did an analysis of 32 million emails sent by their users and categorized the resulting open rates by subject line.

The results are fascinating and somewhat counter-intuitive as less is clearly more:

What Makes a Bad Subject Line?

·       Anything more than 3 words: the chances of your email getting opened drop by over 60%

·       Asking a question: Question marks perform poorly – be more demanding!

·       Using marketing language: Offering the top 10 industry secrets doesn’t work

 

What Makes a Good Subject Line?

·       When in doubt use Re: Don’t bother crafting the perfect subject line. There isn’t one.

·       Keep it very short: Using 1-2 words maximizes your chances of getting your email opened.

·       Be direct, don’t beat around the bush: To introduce yourself use “Intro”.

Remember, that over 40% of emails are opened on a mobile device.  The screen can only fit four to seven words max which can cut off your subject line.
